IMPROVEMENT IN BASE-BURNING STOVES.-

The Schedule referred to in these Letters Patent and making pari: ofVthe same.

To all whom it may concern:

Be it known that we, EsnK BUssEY and CHARLES A. HAMLIN, of Troy, inthecouuty of Rensselaer and State of New York, haveinvented certain newand useful Improvements` in Parlor-Stoves and we do hereby declare thatthe following is a full, clear, and exact description thereof, referencebeing had to the accompanying drawing and to the letters of referencemarked thereon which form apart of this specification.

The nature of our invention consists- First, in lthe arrangement of acoking-chamber above and disconnected from the hre-pot, and connectedwith the fuel-rescrvoirby an open grate.

Second, in the fuel-reservoir, provided with perforations, covered onthe outside with tubes to conduct the gases from the reservoir throughthe grate and into the coking-charnber.

Third, in the arrangement of the cokingchamber, grate, and reservoir,with its perforations and tubes, andan air-chamber and damper.

Fourth, in the arrangement of the top of the stove.

In order to enable others skilledin the art to which our inventionappertains to make and use the same, We will now proceed to describe itsconstruction and operation, referring to the annexed drawing, in\Vl]iC1Al-I Iligdre 1 is a longitudinal vertical section of our stove;

Figures 2 and 3 show'variations in the construction of thefuel-reservoir; and

Figure 4 is a horizontal section through the fuelreservoir.

Figure 5 shows a section of the reservoir-,with one row of perforationsand covering tube on the outside.

A represents the ordinary fire-pot or receivingchamber to receive thecoke made in the cokingchamber B.

lhis coking-chamber B is suspended above and a suitable distance fromthe firepot A, and above said aching-chamber B is a grate, O, to supplythe same with draught, said grate extending close up to thefuel-reservoir or magazine H.

The shell of the stove around theupper portion of the coking-chamber Bis perforated as shown at F,

`leaving an air-chamber, G, between them, thus sup- In thefuel-reservoir or magazine H are made openings J J, which lead into andare covered by pipes or tubes I I, formed on the outside of thereservoir Vfor the purpose of carry-ing olf the waste gases which formin th'e reservoir and prevent them from escaping into the room throughthe upper portion K ofthe stove, said portion being made perforated, asshown, or otherwiseof open work, to prevent the reservoir from becomingheated and the coal from colring iu the same.

The gases carried off from the reservoir by the tubes I pass through thegrate O into the colring-chamber B, the tubes for this purpose extendingdownnear to the lower edge of the grate, and their inner sides leftopen, as shown in iig. 5.

The fuetreservoir- H may be made all open work, with ya casing aroundit, as shown in fig. 2, or it may be made of rings and outside casing,as shown in tig. 3.

L is anvair-tight cover to close the top of the fuelreservoir. Y

M is the out-er cover, hinged or pivoted on one side, so that it can bethrown open when fuel is to be supplied to the stove.

In the top of the cover Mis an opening, O, covered by a hinged cap, P,which may be made -in the shape of an urn.

This cap'is connected with the. cover L by a strip, N, as shown. f

The method of operating the stove is as follows Fire is kindled in theordinary manner in the tire pot A, and draught is admitted below thegrate,as is generally done', the reservoir H, coking-chamber B, and{ire-pot A being all lled with fuel.

After the fuel iu the fire-pot A becomes well ignited the draught belowthe grate is closed. Then the draught is taken iu from the door ordamper at D through thegrate G and colring-chamber B, thence in the ducof the stove. The object of this is to keep up combustion in thecoking-chamber B and pass the gases from the fresh fuel in the reservoirH through the burning coke in the chamber B audoverthe buruing coke inthe pot A, thus becoming highly heated before meeting the currentvofairadmitted through the openings in the gas-ring E.

At the grate C, as crust willfform from the freshv fuel as it is cokingand a small quantity of gas or smoke arise to the top of the magazine,and for the purpose of carrying olf this waste gas, we make the openingsJ and cover them by pipes I, and carry the same to the burning fuell iuthe chamber B, and thence into the lues of L the stove.

When the cap P is in position over the opening O the cover L closes the`top of the reservoirH, preventing the escape of gases from the coalcoming into the room.

' When necessary to add vfreslrfuel to. the reservoir H the cap P `isturned over, which raises the cover L and makes a downward draught,carrying o the waste gases in the reservoirthlough the perforations Jand tubes I, into the chamber B. The outer coverM can .T, which arecovered on the outside by the tubes 1,'

for the purpose of conductingv the gases from said l reservoir throughthe 'grate Gand into the cokingchamber B, substantiallyas herein setforth.

" 3. The arrangement of the coking-chamber B, grate (l, reservoir H withits perforations J and tubes I, chamber Q, and draught-door D, n.11substantially as shown and described.

4. The combinationof the hinged or pivoted cover M with opening O, capl), connecting-strip N', and cover L, al1 substantially as and for thepurposes here in set forth.

In testimony that we claim the foregoing as our own we-ax our signaturesin presence ofjtwo witnesses.
